In these activities, you explore the steps involved in solving systems of linear equations. You’ll make observations about the effects of those operations on the solution sets of the systems. In Part 1, you’ll solve three systems using pen, paper, calculator, etc. In Part 2, you’ll solve the same systems and two others using an interactive tool called the System Solver.
